To all whom it may concern:

Be it known that I, Enwrx S. SHANKLIN, citizen of the United States, residing-at Oakland, in the county of Alameda and State of Califorriia, have invented new and useful Improvements in Resilient Wheels, of which the following is a' Specification. My invention relates to a cushion vehicle wheel. j'.

The objectof the invention isto provide a simple, practical wheel which will have-all the resilient qualities of the ordinary puncturablepneumatic'wheel, without any of the dangers or annoyances incident to the use of the latter;' a

The invention consists-of the parts andthe construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings,- in which- F igure'l -is a ,side elevation partially in section. Fig. 2 is an edge view of the wheel,

, is a cross section through the'inner tube.

-- A represents the hub of my improved wheel having secured thereto the disk or plate 2 which performs the functions of the usual spokes. To the outer edges of this disk is rigidly secured the detachable rim 3, carrying the detachable tire 4;.- This tire is of peculiar construction and may be of the single tube variety, as here shown. As hereshown this tire is entirely housed within the rigid protective plates 5, and does not come in contact with the groundat any time, or at any place, and its outside or tread portion is flan ed and reinforced seas to be gripped by t e bent jaw portions 6 of the plates 5, just as the opposite side of the tireis gripped and held by the rim 3; in other words, this tire is formed with a flat inner portion and .a flat outer portion, each having the laterally extending flanges 7, with the corner portion of these 'fiange members reinforced by the usual hard rubber ring 8. v

The plates 5 are formed with a bulge in dicated by the'inclosed chamber 9 to house '.-in the tire and rim; the plates being brought 7 toward each other again toward the outside to form the gripping jaws 6, and are secure to the outer solid metal rim 10; on the outside of which rim rests the solid rubber or non-punoturable resilient tire 11. sired this tire. 11 may be reinforced by wires 12. j

The outside edges of the plates are bent to form. opposed hook members 13, which" grip the tire l1 andjhold it in place on the rim 10. i The run is provided with enlarged transverse perforations 14 at intervals, through which perforations and through the opposed plates 5, are passed the bolts 15 by which the plates 5 are rigidly bolted to the rim 10.. i

The edges of the plates adjacent to the hub are bent to lie flat, and to slide upcn the spoke plate 2, and between the latter-and the hub flanges l6 17, there being a space 18 as the packing rings 20 are provided at suit able points between the contiguous parts of the plates 5 and 2. This construction 3 also makes it possible to lubricate'the moving plates, as the packing rings keep the lubricant in, as well as keeping dust out.

21 are bolts passing through the plates 5, and working in holes 22, and the spoke plate 2; these bolts 21 being designed to hold the side plates snug against the spoke plate, and give rigidity tothe structure.

The boxes 18 may be lubricated through a suitably plugged opening 23.-

Thus the inside of the tire is gripped by the rim 3 and the outside is gripped at 6 so as to be rigidly connected with the tread portion 11, the full tract-ive forceof the wheel is preserved, and at the same time all the resilient qualities of the use of a pneu- I claim and desire to secure by Letters Patcut isp 1.
